Participate in a Study
hello world!
Direct-to-Patient Site

Access 100% of your target population with the industry's only FDA-Inspected Direct-to-Patient Site

By bringing clinical research to the patients’ home with high quality care, and the detailed execution, delivery, and data collection you expect from your best sites.

The First & Only
FDA-Inspected Direct-to-Patient Site

The First & Only
FDA-Inspected
Direct-to-Patient Site

Five Phase 3 Trials Inspected:

  • No Action Indicated (NAI) classification
  • No objectionable conditions noted
  • No Form 483 issued
  • No recommendations

Clinical Research Has a Patient Access Problem

Traditional brick-and-mortar research sites reach fewer than 10% of eligible clinical trial patients, leaving over 90% outside their catchment areas and often requiring long-distance travel to participate.

The Site That Visits The Patient

Science 37’s Direct-to-Patient Site enables sponsors to reach 100% of their target patient population  by conducting study visits in patients’ homes.

Direct-to-Patient Logistics

50-State Medical Licensure
Single 1572 and IRB Submission
IMP Shipment 
Kit and Study Supplies
Research Nurse Coordination 
Investigator Oversight
With 50-state licensure, our medical teams manage studies nationwide, ensuring broad patient access. This nationwide capability facilitates seamless enrollment regardless of the participant’s location. 
We simplify the approval process by consolidating regulatory requirements into a single 1572 and IRB submission. This streamlined approach reduces complexity, speeding up trial start-up and accelerating the path to First Patient In (FPI).
The Investigational Medicinal Product (IMP) is shipped from our central pharmacy partner directly to the patient’s home 1–2 days before the scheduled dosing visit. Our research-grade nurses ensure full chain of custody is maintained throughout the process.
Lab kits and study visit supplies are shipped from our headquarters directly to the participant’s home 1–2 weeks before the scheduled visit. Our research-grade nurses verify delivery upon arrival.
Our nationwide team of in-house research-grade nurses conducts study visits in patients’ homes. For each visit, the nearest qualified nurse is identified, and our central scheduling team manages all coordination.
Our investigators ensure participant safety and compliance through remote monitoring, in-home nurse visits, and real-time data access, mirroring traditional site investigators in a direct-to-patient model.
